Assessment of CR8020, a Monoclonal Antibody Against Influenza A Viruses

Phase 1

Completed

• Conditions: Influenza
• Interventions: Biological: 2 mg/kg CR8020; Biological: Placebo; Biological: 5 mg/kg CR8020; Biological: 15 mg/kg CR8020; Biological: 30 mg/kg CR8020; Biological: 50 mg/kg CR8020

• Registration Number: NCT01756950
• Lead Sponsor: Crucell Holland BV

Brief Summary

The purpose of this study is to assess in healthy subjects the safety, tolerability, pharmacokinetics and immunogenicity of single escalating doses of CR8020, a monoclonal antibody against influenza A viruses.

Detailed Description

This randomized, double-blind, placebo-controlled dose escalation study will enroll up to 5 cohorts of healthy subjects. Eight subjects will be enrolled in each cohort and will receive a single 2-hour intravenous infusion of CR8020 (6 subjects) or placebo (2 subjects) on Day 1. Subjects will be dosed in pairs of two. Once all subjects in a cohort have completed Study Day 8, the preliminary safety data will be reviewed. Provided that no safety issues are identified, dose escalation to the subsequent cohort may be permitted. After the completion of Cohort 5 enrollment, and the preliminary safety and tolerability of the 50mg/kg dose is demonstrated, a sixth cohort will be enrolled. Cohort 6 will be comprised of 24 subjects (randomized 5:1 to CR8020 30 mg/kg or placebo) who will receive 2-hour intravenous infusions on Days 1 and 8.

Primary Outcome Measures

Name	Time	Method
Adverse events and changes in laboratory parameters and vital signs as measures of safety and tolerability of single escalating doses of CR8020	From baseline to 98 days post-dose

Secondary Outcome Measures

Name	Time	Method
Assessment of pharmacokinetics of single escalating doses of CR8020	From baseline to 98 days post-dose	Pharmacokinetic parameters include area under the serum concentration-time curve from zero to the time of the last measurable concentration (AUC0-t), area under the serum concentration-time curve from zero to infinity (AUC0-inf), maximum concentration (Cmax), time of Cmax (tmax), systemic clearance (CL), terminal elimination half life (t1/2), etc.
Assessment of antibodies binding to CR8020 as a measure of immunogenicity of single escalating doses of CR8020	From baseline to 98 days post-dose
